So far I've seen many "Obama 2012" and Elizabeth "The Fake Indian" Warren bumper stickers on Massachusetts cars, particularly in the Boston area. I have seen those "Obama 2012" and Obama-Biden stickers on cars from other states as well, unfortunately.
I've seen maybe two Romney bumper stickers so far, one was on an Ohio car traveling in Maine on Labor Day weekend.
I've seen NO presidential lawn signs anywhere so far. I do find it strange... we're already into September. I'm assuming (?) that more lawn signs will pop up as we get closer to the election...
No lawn signs at all here in S.W. Ohio area. A few bumper stickers for each side. Prolly people are just FED UP WITH POLITICS
